To all whom it my concern:

Be it knownythat I, Ennasr L. CRoNE- MEYER, a citizen of the United States, residing at Granite City, Illinois, have invented a' certain new and useful- Improvement in, Tin- Plate Catchers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, referings, forming part of this specificatlon, in which Figure 1 is a rear elevation of a tin plate catcher constructed in accordance withmy invention; Fi 2 is a vertical sectional view taken on the line 22 of Fig. Hooking tion of a tin plate catcher embodyin the features of m i-nvehtion and with a den le tinning-maclnne. 1 This invention relates to devices commonly called tin platecatchers that are used 1n connection with tinnin -machines for de-.

'livering afresh 1y coated p ate from the rolls of the tinnmg-machine to-a chute.

is to provide a device fsimple construction of theftinning-mach ine andfdischar e them onto'a chute without .theuse of fee rollers whichh'avea tendency to smirch and near the hotoily plates.

age the freshly coat Briefly described, m improved tin plate catcher comprises endless conveyers pro? vided with small grip ing devices which ene plates as they emerge ine and omthe rolls of the tinning-mac I feed them away from said rolls without markmg or marring the plates. The catcher also preferably comprisesia ribbed deflecting roller "them from buckling or kinking.

lie'l erring to Figs. 1 and 2 of the drawings which illustrate the preferred form of my invention, 1 designates the rolls of the ti nningmachine, and 2 designates the frame of'my improved tin plate catcher which'is mounted on the firmingmachine above the rolls 1 disposed endlessconveyers arranged parallel te each other and rovided with 006 crating gripping devices tiat en age the p ates as they emerge from therol s 1 of the tinningmachine. and feed them vertically away from in the i direction of the arrow; Fig. 3 is an en elevadesigne foruse l or cross bars 3 and the chains 5 bein vided with slats or cross bars 5.

,l i have herein shown conveyers which consist of sprocket chains to which cross bars are conf' nected, I'do not wi'sh'it to be understood that gmy' broad idea is limited to such a construction as the conveyers could be formed in va- 5 rious'other Ways.

The main object of my presentinvention sprocket wheels, and each of said two said rolls. The machine shown in Fig. 1 is adapted to simultaneously feed twoplates arranged side by side from the rolls of the tinningsmachine and is therefore provided with two sets of conveyers A, A and B, B,

- but it. will, of course, be understood that the catcher could be provided with only one pair of conveyers without departing from the spirit of my invention. ence being bad to the accompanying draw- The conveyers A and A consist of sprocket chains 3 that travel over sprocket wheels on shafts 4 and 4 arranged in vertical alinement ,with each other, and the conveyers B and B i consist of sprocket chains 5 that travel over sprocket w eels on-shafts 6 and 6- arranged arallel to the shafts4 and 4 as shown in ig 2, the chains 3 being provided with slats m- 1 e I The conveyers A and A are provided with gripping devices 7, and the conveyors B and that will lift the coated plates from the rolls are provided with gripping devices 8 and when said cooperating gripping devices come into alinement with each other they will engage the plates as they emerge from the rolls 1 of the tinnin machine and feed them vertically to a rol er 9 which deflects the plates v onto an inclined chute 10. The cooperating gripping devices 7 and 8 of the conveyors may be formed of steel, lead, aluminum or any othersuitable material but I refer to 5 form them of steel coated With bloc tin, the r1p hloc that guides the plates to a chute and prevents png devices 7 consisting of flat-faced that are secured tothe cross bars 3' adjacent the ends thereof, and the gripping devices 8 consisting of blocks connected to the cross bars 5 adjacent the ends thereof and having rounded or curved faces. The articular construction of these fgripping devices,

however, is immaterial so idea is concerned. 7

The cohveyers travel over tracks or guides 11 that are carried by bars 12 which are su ported by the horizontal shafts that carr t e provided with laterally projecting shanks 13 that pass through 0 enings in the supporting bars 12. The trac s 11 for the respective conveyers are forced toward each other by as my broad" means of coiled expansion springs 15 'surrounding I mount the shafts 4 and 4 for the conveyers A and A in adjustable bearings 16 that can be moved toward and away from the shafts 6 and 6, thus roviding an additional means for varying t e tension of the gripping devices. The deflecting roller 9 is arranged above the conveyers and is so disposed relatively thereto that it will gradually deflect the plates onto the inclined chute 10 as they emerge from the conveyers, said chute being provided with a smooth or corrugated bottom and side pieces 10 that guide the plates down the chute. The deflecting roller 9 is provided with ribs 9 preferably arranged in alinement with the gripping devices on the conveyers, as shown in Fi 1, so as to engage the ed e, portions of the p ates and thus pre vent t em from bending erpendicularly as often occurs with the tin p late catchers heretofore in use'which were provided with deflectors which consisted of curved rods. The deflecting roller 9.may be formed of wood, metal or any other suitable material and said roller is driven continuously by the sprocket chain 17 which passes over sprocket :wheels on the shaft of said roller and on one of the conv eyer shafts, preferably, the shaft 4. The shaft of said deflecting roller 9 is mounted in movable bearings that can be adjusted horizontally by means of screws 18 and the inclined chute 10 can be adjusted vertically by means of adjustin screws 19.

Various means can l the conveyers and I have herein shown them as being driven by a train of cars that are actuated by a pinion 20 which drives the rolls 1 of the tinning-machine'." The pinion 20 meshes with an ldler 21 that meshes with a gear 22 on one end of the horizontally dis posed shaft 6 and on the other end of said shaft is a gear that meshes with the gear 23 on the horizontally disposed shaft 4, said gears being preferabl proportioned so that the conveyers and de ectin roller will travel at the same speed as the rol s 1 of the tinningmachine.

The gripping devices 7 and 8 on the conveyv ers are so arranged that each plate will always be engaged at at'least four separated points as it 1s passing between the conveyers so that it will eiimpossible for the plate to shift or become displaced, and as the plate is engaged at only a few points and by gri ping devices that have verysmall engaging aces, the hot e employed for driving oily coating on the plate will not be marred or defaced.

In Fig. 3 I have shown a catcher that is adapted to be used with a double or duplex tinning-machine, said catcher being of substantially the same construction as that shownin Figs. 1 and 2, except that additional sets of conveyers C and D are provided for cooperating with the extra set of rolls 1 of the tinnin ,machine, the catcher also comprising an inc ined chute 100 and a deflecting roll 90 that cooperates with the conveyers G and D, said conveyers peing longer than the conveyers A and B so hat the plates will be deflected therefrom at a higher level. The mechanism for driving the conveyers A and B is substantially the same as that shown in Figs. 1 and 2, and the conveyers C and D are driven by means of an idler 21 meshing with the gear 22 and with a gear 27 on the drive shaft of the conveyer D, said drive shaft being provided at its opposite end with a gear that meshes with a gear 28 on the drive shaft of the conveyer C.
